Furnace Noises That Could Mean Trouble

Furnace Noises That Could Mean Trouble

Is your furnace waking you up at night or disrupting your favorite show with clinks, bangs, and clunks? It could be trying to tell you something. Here are some bizarre noises that likely mean you should call someone for furnace repair in Lafayette. 


Banging and Clanging

Sounds you’d categorize as “bangs” or “clangs” could mean there’s a loose component in your furnace. This noise usually only happens when something has shifted out of place. Don’t ignore these sounds; turn off your furnace to avoid doing any more damage to the components and call a professional to put everything back where it belongs.


Hissing and Whistling

If your furnace sounds like a train leaving the station, that often has something to do with the airflow. It could be something as simple as needing to clean the air filter. Or it could be something that needs professional attention, like a malfunctioning blower motor. Clean your filter (because it’s good furnace hygiene anyway), and if the problem doesn’t go away, call a professional for furnace repair in Lafayette.


Clicking

Clicking can have numerous causes — maybe the ignition system is trying to ignite the burners, which isn’t any reason for alarm. But if the clicking persists, that’s a bigger problem. It’s likely stemming from an issue with the ignition system or even a malfunctioning safety switch. Either way, this is another problem you can’t afford to ignore.


Popping and Booming

Probably the most unnerving sound to hear from your furnace is a giant booming sound. And you’d be right to be concerned — this is generally not a good sign and could mean gas is building up in the combustion chamber. If you hear a noise like this, turn off your furnace immediately and call a professional for emergency repair services.
